Bacteria that live in the soil seem to be swapping antibiotic-resistance genes with other, more dangerous bacteria — the ones that cause devastating infections in humans, a new study indicates.
When a team of researchers analyzed bacteria they had grown from soil samples, they found the microbe... Read More
The use of a commonly prescribed antibiotic is a major contributor to the spread of infection in hospitals by the ‘superbug’ MRSA, according to new research. The study also found that increasing measures to prevent infection – such as improved hygiene and hand washing – appeared to have only a s... Read More
This episode: Slime mold cells carry bacteria with them, some for food and some for chemical warfare!
This episode: New giant virus discovered, with a genome larger than that of some eukaryotes!
This Week in Virology, the podcast about viruses, celebrates its 300th episode on Tuesday, August 26, 2014 with a live recording at the Washington, DC headquarters of the American Society for Microbiology. This special episode w... Read More
Lately, we've been learning more and more about the teeming masses of bacteria inside our bodies - essentially trillions of tiny organisms that make us sick and keep us healthy.
Now two scientists at the University of Colorado have dared to ask what kinds of bacteria lives inside our mouths. ... Read More
I comment a bit, as an educator, about the loss of Carl Woese. Not only the importance of his discoveries, but how he went about his work, remains of great value. Read More

A new study of giant viruses supports the idea that viruses are ancient living organisms and not inanimate molecular remnants run amok, as some scientists have argued. The study may reshape the universal family tree, adding a fourth major branch to the three that most scientists agree represent ... Read More
Many species exhibit cooperative survival strategies — for example, sharing food or alerting other individuals when a predator is nearby. However, there are almost always freeloaders in the population who will take advantage of cooperators. This can be seen even among microbes such as yeast, whe... Read More
Current influenza vaccines are limited because they can only stimulate immunity to specific strains of the virus, which is constantly evolving. This means a new vaccine must be developed every year to target the strains public health officials believe will be most prevalent that season. If an un... Read More
Cold Spring Harbor Laboratory has been named a Milestones in Microbiology site by the American Society for Microbiology. This ASM program recognizes institutions and the scientists who worked there that have made significant contributions toward advancing the science of ... Read More
Dr. Jeffrey Almond began his career as an academic virologist studying influenza. Eventually Jeffrey started his own lab and began studying picornaviruses working on an oral polio vaccine strain.
Following twenty ... Read More
Nearly one third of forestry workers in parts of eastern France are infected with Hepatitis E virus (HEV), according to a paper in the September Journal of Clinical Microbiology. Wild boars in the same region are also heavily infected. HEV is endemic in developing nations, but heretofore, HEV in... Read More
A mysterious condition called Inclusion Body Disease (IBD) strikes captive boa constrictors and pythons, causing bizarre behavioral changes and eventually death. Scientists investigating an outbreak of IBD among snakes at the Steinhart Aquarium in San Francisco report they may well have found a ... Read More

The Gram stain is commonly used in epidemiologic and clinical studies. It involves smearing a sample onto a slide, staining the material using dyes that bind to bacterial cells, and visually inspecting under a microscope. Many epidemiologic and clinical studies of pregnancy, sexually transmitted... Read More
